fixes #107: client utils were possibly not yet being injected and available when calling Capser.base64encode() from some events

merged PR #96: make python launcher use os.execvp() instead of subprocess.Popen() (@jart):
> This patch fixes a bug where casperjs' python launcher process won't pass along kill
> signals to the phantomjs subprocess. This patch works by using an exec system call
> which causes the phantomjs subprocess to completely replace the casperjs parent
> process (while maintaining the same pid). This patch also has the added benefit of
> saving 10 megs or so of memory because the python process is discarded.
